Quarantined - AntiVirus Check

  • Antivirus is required to access the eduroam network for Linux devices.  
  • There maybe multiple antivirus software available for Linux, however, we recommend ClamAV.

Install any supported Antivirus application

*** The installation of ClamAV may require full internet connectivity.  If issues occur, ITSS can assist in getting this installed correctly while on campus or the steps can be completed while connected to off-campus networks.

1. Confirm the message below is shown. 

  • This is the only Clearpass Quarantine message that should be seen on Linux.
  • Contact ITSS in MLIB 142 or via phone 530-898-4357 if there is a different message.
